PTFE membrane discs are perfectly suited for laboratory scale filtration of aggressive organic solvents, concentrated acids, alkalis, and cryogenic fluids, which would attack other filtration membranes. They are also well suited for air sampling and particulate analysis.

Memtrex FE absolute pleated cartridge filters, with absolute rated polytetrafluoroethylene (PTFE) membranes, offer broad chemical compatibility with minimal extractables in a wide range of fluids and applications. The inherently hydrophobic PTFE membrane is ideally suited for the filtration of compressed air and other process gases.

Hydrophilic PTFE membrane pore size is 0.22μm, 0.45μm and chemical compatibilities are superior to aqueous, organic solvents and mixed solvents. Hydrophilic PTFE membrane is the strongest membrane filter for strong acid, alcohol, and so on. Hawach has a full range of Hydrophilic PTFE membrane filters, diameters, and pore sizes that can be

Filtration membranes may be composed of nylon, polypropylene, cellulose, nitrocellulose, glass fiber, and PTFE. Nylon filtration membranes are chemically compatible with a wide range of solvents. Polypropylene filtration membranes are used with more aggressive solvents. Because these membrane filters are highly adsorbent, they’re also a good

PTFE Membrane is unaffected by almost all liquids, including organic solvents, concentrated acids and bases, propellants, and cryogenic fluids. Mitex™ membrane is unbacked, yet is easy to handle, combining the convenience of a backed membrane with the versatility of a pure PTFE membrane.

PTFE membrane filter is made of polytetrafluoroethylene ultrafine fibers by hot-melt bonding together. Difference from glass fiber membrane, PTFE filter is a kind of membrane material for deep filtration. Membrane filter disc has the following characteristics: membrane filter 0.22 μm is produced from food-grade isotactic polypropylene. See full list on hawachmembrane.com

To meet these challenges, PTFE membranes are extremely durable with superior chemical resistance to many aggressive media and corrosive solvents. PTFE membranes are resistant to temperature up to 500°F and are naturally hydrophobic.

Aug 07, 2018 · Polytetrafluoroethylene (PTFE) Membrane. Hydrophobic, highly inert, and durable, PTFE is a popular material with a wide operating temperature range and resistance to the damaging effect of many chemicals. When should you use it? DO USE: for filtering solvents and other aggressive chemicals, such as acetone and DMSO.

Aug 15, 2011 · Membrane stripping of carbon dioxide from an aqueous 30% (w/w) potassium carbonate solvent was achieved using two types of polymeric flat sheet microporous membranes; a polytetrofluoroethylene (PTFE) membrane and an asymmetric polyether sulfone membrane with a proprietary hydrophobic surface coating.

High-purity PTFE membrane filter media provides superior chemical resistance for a broad range of industrial applications. With retention ratings as fine as 0.01μ (10 nanometers), consistent contaminant removal is achieved in aggressive fluids and organic solvents.

PTFE allows air to pass easily through the membrane while collecting particulate as small as 0.1 micron on its surface. PTFE membranes provide device manufacturers with a consistent, temperature and chemical compatible barrier to microbes and particulate matter.

Whatman PTFE membrane filters from Cytiva's business are chemically stable and inert, making them suitable for use with aggressive organic solvents, strong acids, and alkalis. Order Product. ×. Select Model. ID. Product Name. 28415319. PTFE Membrane, TE Range (TE 35), 0.2 µm pore size, 25 mm circle (50 pcs) 28415320.

PTFE membranes are a thin, unsupported, highly porous film that offers maximum chemical and pH resistance to a broad range of aqueous and organic solvents. This membrane exhibits high flow rates with minimal aqueous extractables(<0.3 wt%).
